Abstract (en)
[origin: US2009171333A1] Systems and methods for controllably delivering liquid coolant such as nitrous oxide to an ablation device for cryogenically ablating tissue. A cooling element liquefies gaseous coolant released from a coolant supply or tank. An actuator in fluid communication with and between the cooling element and the ablation device defines a chamber. Liquid coolant is controllably drawn into and controllably expelled from the chamber for delivery to the cryo-ablation device. Liquid coolant can be controllably drawn into the chamber from the cooling element or from a container or reservoir that stores liquid coolant generated by the cooling element.
